Result: Durham (325 & 160/9; Killeen 22*) beat Leicestershire (242 & 242; Randhawa 7/69) by one wicket
Seven wickets for Gurman Randhawa and an unbeaten 22 from Neil Killeen saw the Seconds to a nailbiting one-wicket win over Leicestershire.
Having started the day on 135/5, Leicestershire boosted their score up to 242 and on par with their first innings total.
It left Durham needing 160 to win and they looked to be home safely until a string of middle-order wickets.
And it was left to Killeen, stepping in due to the absence of Stuart Poynter on First XI duty, to steer his side home with a wicket to spare.
Randhawa started the day with 3/22 and added four more on the third morning, finishing with figures of 7/69.
Durham's reply started strongly and though they lost Nick Hobson for six, Adam Hickey and Calum MacLeod both made 28.
But a spate of single figure scores left them on 124/8 and still 36 runs short when Killeen strode to the crease.
Another wicket fell but he was joined by Gurjit Sandhu, who made six not out, and the pair saw it home in a tantalising finish.
